Available in PDF, EPUB and Kindle. Book excerpt: A small, uncooled research rocket motor was built to study the effects of a vortex flow on combustion instability. Normal heptane and air were used as propellants with the air being divided into two flows; a primary flow at the center of the combustion chamber and a secondary flow at the periphery of the chamber. The secondary air provided the swirl which could be directed clockwise or counterclockwise at various angles or a straight mode of operation. Runs were made at various flow rates with the direction of swirl changed during the run. A first tangential high frequency mode of combustion instability was developed and a significant change in stability conditions was found when a vortex flow as generated within the combustion chamber. It was found that a swirl in one direction tended to decrease the instability while a flow in the opposite direction increased it. (Author).

This book was released on 1971 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: A small, uncooled liquid rocket motor was utilized to examine the effects of the magnitude and direction of a steady vortex velocity on combustion instability. The rocket operated on normal heptane and air, with air flow rates controllable to allow for various amounts of tangential momentum. Results of the investigation indicated that an energy feedback mechanism, through tangential momentum, did exist for both tangential and radial modes of instability. It was further shown that limit values of tangential velocity did exist, for a particular combustor, above and below which instability did not occur. (Author).

Book excerpt: Progress in Astronautics and Rocketry, Volume 6: Detonation and Two-Phase Flow compiles technical papers presented at the ARS Propellants, Combustion, and Liquid Rockets Conference held in Palm Beach, Florida on April 26-28, 1961. This book provides an excellent illustration of research and development on a selected group of problems relating to detonations, two-phase nozzle flow, and combustion in liquid fuel rocket engines. This volume is divided into two parts. Part 1 covers the entire range of physical conditions under which detonation may be initiated or sustained, such as high explosives, solid propellants, liquid sprays, and gases. Experimental and theoretical studies are also discussed, including the significant progress of the basic phenomena involved in transition from deflagration to detonation, and nature of stable detonations in dilute sprays and other systems. The perennial problems associated with high frequency instabilities in liquid fuel rocket engines are considered in Part 2. This publication is valuable to students and investigators working in the field of propulsion research and development.

Available in PDF, EPUB and Kindle. Book excerpt: The objectives, work carried out and results obtained during a Phase 11 STTR project are reported. An capability for unsteady flows is added to a sensitivity tool which numerically solves the continuous sensitivity equations. A feedback control law is implemented to control numerically an acoustic instability, which is modeled by coupling pressure and velocity perturbations at an inflow boundary condition. Axi-symmetric simulations are presented for the burner both without methane injection and with five injection locations. The computation is performed using a 12-specie methane/air chemistry model with finite-rate chemical kinetics. An experimental investigation is pursued of a circular bluff-body burner equipped with multiple fuel injectors. The axial injector is used as a pilot flame for premixed observations at equivalence ratios of 0.4 and 0.5.
